Definitions
- Illumination unit 54 includes a halogen lamp light source 54a which is supplied with current through a cable 66.
- fiber optic illumination may be provided by means of an external light source and a fiber optics cable.
- Light source 54a produces an illumination beam 54b which, as explained below, is directed toward eye 11 to illuminate the latter.
- An optical aperture or window 70 through which light passes between the patient and the observer is closed by a plain glass disk 71 to prevent the intrusion of dust into observation unit 52.
- a single lever 72 which is centrally located relative to observation unit 52 and equally accessible to both left-handed and right-handed users, can be used to simultaneously set the position of the images of the examiner's pupil (i.e., the observation beams) and the position of the image of the light source (i.e., the illumination beam) in pupil 11 of the patient, i.e., convergence and parallax.
- a pair of windows 80a and 80b are provided in a pair of side portions 84 of binocular ophthalmoscope 400 to allow third parties to view the image represented by light rays 12 and 13, respectively.
- Windows 80a and 80b are each provided with a sliding door 82 to open and close the associated window.
- cam surface 101c engages support bar 114a so as to move support backing 112 upwardly or downwardly in linear reciprocating directions which are perpendicular to the linear reciprocating directions traveled by members 100, 101 and 102.
- Support bars 114a and 114b are in continuous contact with a cross bar 118.
- a resilient spring-like member 120 which includes a pair of arms 120a and 120b is connected to cross bar 118 and provides the bias for continuous contact with support bars 114a and 114b.
- a connection tab 122 is connected to arm 120b in any well known suitable manner.
- Arm 120a includes fingers 120c which rest on mirrors 35a and 35b.
- a pair of screws 120d (shown in FIG. 4) extend through a pair of openings 120e of arm 120a (shown in FIG. 6) and are suitably secured to fixedly position member 120 relative to mirror carrier 90.
